Results of 535 tympanoplasties in various age groups were analyzed by several assessment methods and by calculating the mean postoperative hearing, hearing gain, air-bone gap, and speech audiometry. Analyzed separately are 269 dry ears treated by tympanoplasty without mastoidectomy, and 266 discharging ears treated by tympanoplasty with mastoidectomy in the same stage. The results were far better for dry than for discharging ears; the best results were found in children under 10 years of age. Among the 11- to 30-year-old patients the results were very good for dry as well as for discharging ears. Good results were still obtained in the 31- to 60-year-old patients with dry ears, but somewhat poorer results for discharging ears. Over 60 the results were poorest, and considerably poorer for discharging than for dry ears.
